БЕТОНОВОД ДЛЯ ТРАНСПОРТИРОВАНИЯ И ОДНОВРЕМЕННОГО ЭЛЕКТРОРАЗОГРЕВА БЕТОННОЙ СМЕСИ

摘要

FIELD: civil engineering; production of construction materials. ^ SUBSTANCE: proposed concrete conveying pipeline is provided with tubular sections made of dielectric and installed in end and heaters in form of electrodes, each being arranged at angle of 120° relative to the other in cross section and connected to one of phases of three-phase supply source. Each section is provided with independent ON/OFF switch. Width of each electrode and distance between electrodes is 1/6 of size of inner circumference of pipe section, and length of each electrode is less than length of section by value equal to width of electrode. ^ EFFECT: increased heating power, facilitated manufacture of sections. ^ 6 dwg
